Specification of Letters Patent.

Patented Aug. 28, 1906.

Application filed April 14, 1906- Serial No. 311,633.

To aZZ whom, it may concern:

Be it known that I, RUnoLF BLUMENFELD, a citizen of Austria-Hungary, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Igniters for Gas- Lamps, of which the following is a specification.

My invention relates to improvements in igniters for gas-lamps, and is especially de signed for use in connection with carbid, acetylene, and other gas-lamps used in connection with automobiles and other vehicles.

The primary object of my invention is to enable such lamps to be ignited by means of simple and eflicient mechanism without the use of matches, &c., which require the opening of the lamp for such purpose.

With this end in view the invention consists in the novel construction, arrangement, and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the ap ended claims.

eferring now to the drawings, forming a part of this specification, Figure 1 is a front elevation of an ordinary lamp of this class equipped with my improved igniter with the glass and reflector of the lamp removed. Fig. 2 is a longitudinal sectional view taken through line 1 1 of Fig. 1 with removable reflector inserted in the lamp. Fig. 3 is a detailed view of the rear portion of the removable igniting mechanism.

Similar numerals of reference designate like parts throughout all the figures of the drawings.

Referring now to the drawings, 1 designates the body of an ordinary lamp of this class provided with a burner-head 2 and the usual connecting gas-tube 3. The removable reflector 4 is provided with an opening 5 to receive the burner-head 2, and a cylindrical cup or body 6 is mounted about the upwardly-extending shank portion 7 of the burner formed at the front portion of the lamp, and said cup portion 6 is provided with a housing 8 in front of said shank portion 7 and is adapted to receive and contain the removable igniting mechanism, consisting of a main body portion or plate 9, provided with integral side walls or flanges 10. The main body portion or plate 9 is provided with an opening adapted to receive and contain a stem portion 11, carrying at one end a ratchet-wheel 12, suitably secured thereto,

and provided at its other end with a peripherally-flanged disk 13, having a series of longitudinally-extending recessesor slots 13. (See Fig. 3).

A narrow paper band 14 is wound about a pin 15, mounted beneath the disk 13, and said paper band 14 is provided with a series of percussion-caps and extends upwardly and over and about a fixed plate or anvil 16, and thence downwardly and wound over and about the flanged portion of the disk 13, one end of the paper strip being secured in one of the slots or recesses 13 therein, as shown most clearly in Fig. 3 of the drawings.

A spring-arm 17 is secured at its lower end to the side walls or flanges 10 and is provided at its upper end with an elongated strikingarm or hammer-head 18 adapted to strike down upon and explode the percussion-caps of the paper strip 14 when the latter is moved over the fixed plate or anvil 16 as hereinafter described. The spring-arm 17 is provided at its side with a short arm or flange 19, adapted to rest upon and be moved by a series of teeth 20 of the ratchet-wheel 12.

The ratchet-wheel 12 is moved by means of a vertically-arranged sliding arm 21, provided at its upper end with a hooked arm 22, adapted when pulled downwardly to engage one of. the teeth 20 of the ratchet wheel, whereby the revolution of the same will cause one of the other teeth .of the ratchetwheel to depress the spring-arm 17, as shown in Fig. 3, so that when the vertically-arranged arm 21 is pulled down it will move the ratchet-wheel so as to move a tooth of the ratchet-wheel past the flange 19 of the spring-arm 17, whereby the elongated arm or hammer-head 18 will explode the percussioncap as it springs down upon the fixed plate or anvil 16.

The plate or main body portion 9 of the igniting mechanism is removably secured within the housing 8 of the cup portion 6 by means of a fixed shoulder 23 at one side thereof and at the other by means of a shoulder 24, secured to the free end of the vertically-arranged spring-arm 25, having its lower or base end secured to the side wall or flange 10 of said plate. When the fixed plate 9 is placed in position in the housing 8, the shoulders 23 and 24 are adapted to take under and engage the top of the cup portion 6, and as a further means of directing the sparks arising from the percussion of the cap toward the gas surrounding the burner-head 2 a deflector-plate 26 may be formed at the upper portion of the plate 9, as shown most clearly in Fig. 2 of the drawings.

The distance apart of the percussion-caps on the paper strip should correspond substantially with the distance apart of the teeth of the ratchet-wheel, and it will be observed that in order to provide for insuring the ignition of the percussion-caps at all times that the fixed plate or anvil. 16 and hammer-head ing-surf'ace on the paper'strip.

Having thus described my invention without having attempted to set forth all the forms in which it may be made or all the modes of its use, I declare that what I claim, and desire to secure by Letters Patent, is
